CROSSCUT-SAW-FILING TOOL.

Specification of Letters Patent.

Patented June 18, 1912.

To all whom it may concern:

Be it known that I, MINOR J. HENDERSON,

l a citizen of the United States, residing at Tiadaghton, in the countyof Tioga and State of Pennsylvania, have invented a new and usefulImprovement in Crosscut-Saw Filing Tools, of which the following is aspecification.

This invention relates to a cross cut saw filing tool the object beingto provide a tool especially adapted to be used by unexperienced sawfilers for gaging the raker teeth and jointing the tops of the cuttingteeth of cross out saws.

Another object of my invention is to provide the tool with an indicatinggage for gaging the raker teeth whereby the gage of the teeth can bereadily taken so that all of the same can be filed to an even length.

Another object of the invention is to provide very novel means foradjusting the raker gage plate whereby the same can be easily andquickly adjusted and locked in such a manner that all danger of the samemoving is prevented.

A still further object of the invention is to provide novel means forholding the saw in such a position that the jointing of the teeth can bereadily accomplished.

With these various objects in view, my invention consists of the novelfeatures of construction, combination and arrangement of partshereinafter fully described, pointed out in the claims and shown in theaccompanying drawings, in which Figure l is a side elevation of myimproved tool showing the saw in position to have the raker gage teethfiled. Fig. 2 is a side elevation of the same taken from the oppositeside. Fig. 3 is a side elevation of the tool inverted showing a sawindotted lines in such a position that the depth of the raker teeth can bereadily gaged, and, Fig. 4: is a section taken on line 4-4 of Fig. 2.Fig. 5 is a section taken on line 5-5 of Fig.1.

In carrying out my improved invent-ion, I employ a plate A provided withoutwardly projecting flanges B and C at its upper and lower edges whichextend out wardly therefrom in opposite directions and the flange B isnotched together with the plate A in which works the slotted angled endof a gage plate D which is provided with spaced parallel slots D throughwhich extend screws D working in bores formed in the plate for lockingthe gage plate in its adjusted position and it will be seen that byloosening the screws the plate is free to move up and down. Arrangedunder the lower end of the plate D is a plate E which is provided withoblique slots E through which screws E extend so as to slidably mountthe plate E on the plate A so that when the same is moved longitudinallythe gage plate D will be raised and it will be seen that by this mannerby shifting the plate E the raker gage. plate D can be readily adjustedby tightening the screws of the respective plates in a rigid position.The plate A is provided with spaced ribs A against which the side of thesaw is adapted to rest when the tool is placed on the same, the cuttingteeth resting against the under edge of the flange B and the raker teethextending up through the slot in the gage plate D so that the same canbe readily filed. It will be seen that by this construction the rakergage plate can be readily adjusted and locked in its adjusted positionby simply moving the plate E, it of course being understood thatthescrews are loosened first and tightened after the plates have beenadjusted.

In connection with the tool I alsoprovide an indicating gage for gagingthe raker teeth so that after they have been filed the tool can beplaced on the saw in such a position that each ofthe raker teeth can bemeasured so that they will all be cut evenly. For accomplishing this Iprovide the flange C with slits the intermediate portions being bentupwardly to form a tongue F the face of which is provided with adove-tail shaped groove F in which is slidably mounted an indicatinggage G which is locked in its adjusted position by a set screw G workingin a bore communicating with the slot formed in the tongue. The face ofthe indicating gage G is graduated and the face of the tongue to eachside of the slot is also graduated so that the gage can be readily setand adjusted to ascertain the length of i the raker gage teeth. It is ofcourse understood that when this indicating gage is used the tool isreversed so that the flange C is at the top and extending outwardly fromthe plate upon this side is a central rib H which is slotted so as toallow the plate E to move freely under the same and against which theside of the saw is adapted to bear, said plate being also provided withlugs I and pins J which also form bearings for the side of the saw wherethe same will be held in position so that the indicating gage can bereadily used upon the teeth. For jointing the saw teeth I provide theplate A with a shoulder K in alinement with the pins J against which thefile is adapted to be clamped by a clamping member L which comprises aplate having angled ends which is slidably mounted in the slot formed inthe central rib H one end of which is provided with a threaded borethrough which extends a screw M which is mounted in a threaded boreformed in the rib II and it will be seen that after the file is placedagainst the shoulder and pins by tightening up on the screws the angledend of the plate will be brought against the file so as to securelyclamp the same in position so that the same can be used for jointing thecutting teeth with the file.

From the foregoing description it will be seen that I have provided across cut saw filing tool which is provided with a raker gage, a gagefor gaging the raker teeth after they have been filed and a clampingmemher for holding the file for jointing the teeth.

hat I claim is:

1. A. saw filing tool comprising a plate provided with an angled flangeatone edge having a notch registering itha notch formed in the plate, aslotted angled gage plate slidably mounted on one side of said plate theangled portion extending into said notches, means for locking saidplate, a third plate arranged under said raker gage plate provided withoblique slots, screws extending through saidbblique slots working inbores formed in the first mentioned plate whereby said raker gage platecan be adjusted by moving said second plate longitudinally with respectto the first mentioned late. p 2. A device 'of the kind describedcomprising a plate having-a flangealong one. edge at right angles to'theplate, said flange and plate being centrally notched, a r'aker gageplate having the angled end'portion resting in the notch of the flangeof the first mentioned plate, said raker gage plate having a verticalmovement, and a third plate having an oblique sliding movement upon thefirst mentioned plate, the raker gage plate resting 'upon the upper edgeof the last mentioned plate, together with means for locking the saidlast mentioned plate in adjusted posit-ion.
